IMPROVEMENT IN PADDLE-WHEELS.

Specification forming part of Letters Patent No. 179,521, dated July 4, 1876; application filed March 13, 1876.

To all whom it may concern:

Be it known that-I, RICHARD D. CAUTHORN, of WVaverly, in the county of La Fayette and State of Missouri, have invented a new and useful Improvement in Paddle Wheel, of which the following is a specification Figure 1 represents a top view, and Fig. 2

a side View, of my improved paddle-wheel for steamboats. v

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide for steamboats an improved paddle stern-wheel, by which the boat may be turned around by the action of the wheel, without being prop pelled forward or backward, for the action of the rudder, as in the common stern-wheel boats, while also an easier motion of the boat is obtained.

The invention consists of a paddle-wheel applied to the stern, and made of two separately-revolving sections whose buckets or paddles are supported at symmetrical angles of inclination toward the longitudinal axis of the vessel. p

In the drawing, A and B represent the two wheel sections, whose shafts G and I) turn in bearings of outer and central supports E at the stern of the boat. The wheel-sections A and B are made of paddles or bucking of the buckets from the Water the pressare of the dead water diminished, by which an easier motion of the vessel is obtained, as when the paddles-are parallel to the shafts and at right angles to the axis of the ves sel. wheels are preferably connected on the central supporting-frame by a swivel-point which allows either shaft to turn independently of the other. The separate ret olving of the wheels by the machinery of the vessel admits the governing ofthe boat by means of the wheels without the rudder, so that by revolving one wheel only the boat may be turned in its place, without requiring a considerable forward or backward motion to produce, in connection with'the rudder, the swinging around of the vessel. The vessel is thereby more completely within the control of the pilot, which is of special advantage in river and other navigation where the channel is more or less contracted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A paddle stern-wheel, made of two sections with separately-revolving shafts, and buckets or paddles, placed at an angle of inclination symmetrical to the axis of the vessel, to produce by the separate working of the sections the'turning about of the vessel without the rudder, substantially in the manner and for the purpose set forth.
